World Embryo is a manga by the creator of Chrono Crusade, Moriyama Daisuke.Riku Amami, your average Ordinary High School Student, receives a call from his long-lost aunt and stepmother's younger sister, Amane. She asks him to meet her in the hospital he was hospitalized at several years ago. When arriving there, he hears a woman scream. Thinking it is Amane, he instead finds a gang of criminal youths who are attempting to rape a girl. Meanwhile, his entrance into the hospital has been spotted by two other young people, Rena and Yohei. They save Riku from the criminal youth gang, who run off. Yohei is revealed to be one of Riku's old friends from the period he was hospitalized.Suddenly, all mobile phones in the building ring. Riku tries to answer his, but is stopped by Rena and Yohei. The youth gang, whose leader was just phoning for reinforcements on his mobile phone, do move to answer their phones. Just then, their leader's eyes split vertically, the eye halves turning away from each other, while his body is shaking. The other gang members notice this and ask what is wrong.Cue next scene where a horrible monster with the gang leader's transformed face shows up behind the window behind Riku. Holding the shredded corpse of another gang member. Rena and Yohei see this, and Riku turns around. Seeing the horrible creature, Riku screams in horror and flees, still holding his mobile phone. Yohei tells Rena to deal with the monster, called Kanshuu, and goes to look for Riku. He finds him, but they are attacked by more Kanshuus. Riku flees again as Yohei defends him. Elsewhere in the building, Riku is attacked by another Kanshuu and then finds a mysterious cocoon, which once Riku touches it promptly kills the Kanshuu. The next day Riku wakes up in his bed and wonders if it all was a dream. Then he spots the cocoon sitting next to his bed...Later that day at school, Riku remembers what happened at the old hospital. Remembering the monsters, and thinking of the cocoon, he realizes it too could contain a monster. He goes home, only to find his step-mother cowering on the table holding a frying pan, because some horrible creature is wandering around. After some hijinks involving his step-mother and the cocoon, he touches it again, and something emerges from the cocoon. Not a monster, but a little girl closely resembling Amane when she was only a kid...After that, he enters a world beyond the scope of memories, filled with sorrow and heartwarming moments, all leading up to the Embryo.A character sheet is in the works.
This manga provides examples of:
Absurdly High-Stakes Game: The fate of the world rests on the Jinki users being used as pieces in what's basically a board game.
Takao was the very picture of The Stoic; he fights and murders without the slightest change in expression. However, once Youhei asked him for a spare Jinki core to save Riku, he completely loses it.
Bifurcated Weapon: Riku's weapon changes into one after getting a second Jinki core. The sword guard detaches from the hilt and can be used as a dagger.
Big Bad: The Contamination Source, otherwise known as Shirou.
Bigger Bad: Nenee when finally able to reach adult form becomes this.
Big Brother Attraction: Between Riku and Amane. Deranged and creepy version, considering Riku's behaviour in his flashback to when he was younger.
Bilingual Bonus: In Japanese, Cage is written as Keiji. The characters used to write keiji have to do with the sphere of consciousness that resonates within a person.
Body Horror: Transforming into a Kanshuu. Except Kanshuu-Riku, whose transformation only included some minor changes.
Same thing also happened to Kurosawa; It's safe to assume that at least one person who got close to the Coffin Princess will be spared from being mindless Kanshuu.
Later it is revealed that Jinki are pieces of Julie, another Coffin Princess, which explains why it stop Jinki users from becoming mindless Kanshuu
Breaking the Fourth Wall: Nagase does this after catching Rena with his Jinki as she fell off a building. She is then hanging upside down with the Jinki wrapped around her leg with the tip close to her crotch (Does This Remind You of Anything?) and he makes a comment that it is not a very flattering position to be shown in in a manga.
After a 9-chapter flashback, one character complains, "Feels like you've been telling that story for at least 9 months."
Brother-Sister Incest: Riku and his (step)-sister Amane. Averted when Amane tells Riku she'll decide what her answer is after she has done what she has to do. Which never happens due to her disappearance.
Brown Note: The phone call that turns people into Kanshu seems to be an auditory version of this.
Seriously starting with Riku and Neene's shower scene, when she first suggests Riku might be a Lolicon, and then continues when Riku throws water over Neene's head, prompting Shizuru to burst into the bathroom, suggesting she has been listening at the door the whole time.
Ms. Suzu, Hayato's maid. She blushes when talking about Hayato's bath, and has some other little slips when take care of him.
The poor Jinki User who got shredded in Chapter 69, and everyone else that meets the black beast..including Nanami.
Defensive Feint Trap: Subverted with Riku in the first volume. Of course it fails and he gets his ass kicked. Double subverted when Yohei and Rena show up.
The Ditz: Shizuru, at times. Especially the breastfeeding Neene episode. One has to wonder how she survives at work.
Defrosting Ice Queen: Arisugawa's character development. Bonus points because her nickname is actually Ice. (Arisu—>Aisu—>Ice)
Draco in Leather Pants: In-universe example: Takao. He reportedly killed seven people on a train to try out his new sword and killed fifty of his schoolmates during his graduation ceremony... and he's extremely popular among the netizens and the teenagers.
Emotion Eater: Embryo and related stuff. Memory eater, to be exact.
Enemy Mine: Takao and Ende are working together against the new threat. Which is Neene
Face Palm: By Riku, in reaction to Shizuru. Repeatedly.
Foregone Victory: Rena and Riku's fight end up with one of these for Rena. She doesn't like it, because Riku let her win.
Foreshadowing: Whenever Neene has dreams of her ascending some stairs, Amane pulls her back. Similarly, when Ende tries to deny Neene's access to the embryo, Amane appears, and Ende is visibly shocked. Cue chapter 72, with the revelation that Amane is the third, true Coffin Princess.
Freak Out: Being betrayed by Takao is the last straw of Kurosawa's mind; he decided then that all Humans Are Bastardsand executing his plan to destroy Hatsumi Island.Well, while actually Takao is more like "getting caught" than "actively betraying".
Rena when seeing her past, when she saw herself manipulating her father and refusing to help her family out of selfishness. Well, refusing to be sacrificed, but it's a Survivor Guilt.Grown-up!Neenee bring it up again in chapter 73.
Heroic Sacrifice: Yohei gave his Jinki core to Riku to stop him turning into a Kanshuu, turning himself into a Kanshuu in the process.
Neene sacrifices herself to stop rampaging Ende. Made more poignant with her calling Riku a liar, while it is clear that he begin to sincerely cares for Neene, not just as Replacement Goldfish for Amane.
Rena's family tried to indoctrinate Rena to do this if Julie ever went out of control. Rena hates them for it.
Time will tell if he'll go through with it, but Riku holding himself hostage seems to indicate a willingness to pull this off.
Likes Older Women: Riku has been accused of this...and considering that Amane was older than him and his interest in Nanami, they may have a point.
Lotus-Eater Machine: Evil!Nenee traps most of the cast in one as part of the game to decide the fate of the world around chapter 83.
Love Makes You Evil: Karasawa only wanted to revive Ende in order to reunite with Sayoko. He ends up killing countless civilians, turning people into Kanshu, and inducing Lost Rebound in their relatives to do it.
Obliviously Evil: Grown-up!Neene doesn't really understand the consequences about taking people's Jinki's core. To make it worse, it seems that the entities that communicate with her this whole time is only concerned about reviving the embryo, consequences to humanity be damned.
She got a point, though, last time she listen for infected people (her fiancee) it backfired spectacularly, and she ended with abortion and inability to pregnant,
Takao, why'd you just keep hunting Jinki Users indefinitely, instead of talking with them?!
Justified: The Jinki was born of Julie's death. To revive Julie, he has to gather every last Jinki nucleus in the world. Jinki Users turn into Kanshuu should they lose their nucleus. Make of that what you will.
Replacement Goldfish: Coffin Princesses. Born by imprinting a dead person onto a cocoon, they grow into a clone of the said person that grows quickly and gains memories of the people they copied by eating other people memories. Neene is Amane's, Ende is Sayoko's, and Julie is Takao's mother's.
Riku and Nanami for their respective Older sister and Younger brother.
To the Pain: Riku's tactics for getting information. Not that he'll really going with it....
Trauma Conga Line: Poor Riku. A classmate dies as a result of his lies, which gets him to start doubting his actions and lose control of his emotions. Then Neene disappears in front of his eyes, protecting him and Rena, just as he realizes how precious she is to him, not as a means of bringing Amane back but as Neene herself. After that, Karasawa indulges him in a little information via flashback - that he and Riku were pretty much identical to each other. This breaks him even further, compounded with the grief from having lost Neene. He bounces back a bit after returning, though, in which he then gives up on Amane and decides to embrace his present, especially the people important to him now. Nanami, the one who made him have that realization, then dies, and he and Rena arrive on the scene just long enough to see her body disintegrate to dust, save her decapitated head. Intent on having his revenge, he chases after the Kanshuu responsible, only to stumble onto a very much alive and older Neene - who is then taken over by Amane, and is revealed to be a Coffin Princess. Even worse, Amane reveals to him that everything up until that point was thanks to Riku's actions after having received Amane's text message calling out to him - and because of that, indirectly or directly, he was responsible for all the deaths and destruction that have occurred.Poor kid just can't catch a break.
Poor Rena as well.
True Companions: Quite a recurrent theme among the F.L.A.G. members, especially Joe. Riku doesn't really buy it.
Unstoppable Rage: Takao, after Yohei asked him the wrong thing. It didn't turn out well for both of them.
Also Riku has his moment in Chapter 52.
Unusually Uninteresting Sight: Neene and Kanshuu/Jinki Riku's ears. The first time anyone at NEFT mentions Neene's extra ears is when she's stuck in an MRI machine, but they're obvious any time she isn't wearing a hat. This is especially bizarre considering NEFT was scrambling to figure out the source of infection when Riku was still a Kanshuu-thing, when he and Neene had the same peculiar ears on their heads in the middle of a heavily monitored anti-Kanshuu safe room. Probably working as intended, however, as it has since been revealed that Neene can make you forget that you're looking at her while you're staring at her.
Was It All a Lie?: Riku questions this after it is revealed that he had been manipulated to raise Neene.
Wham Line: Chapter 67, starting up another mystery
Riku: Tougo-kun said that you(Shizuru) and Amane-nee aren't really sisters...
Chapter 71, after Riku finds Neene
Neene: Good Morning, Papa...
Chapter 73 brings again this world-shaking lines:
Neene: You managed to come all this way just with that text. I knew I could count on you to do it.
SHUT THE HELL UP YOU FUCKING BITCH!!! WHAT'S WRONG WITH IT?! WHAT'S WRONG WITH PEOPLE ENTRUSTING THEIR HOPES!? SHUT UP AMANE-NEE!! I'VE BEEN LISTENING TO YOU TALK ALL HIGH AND MIGHTY!! ACTING LIKE YOU'RE SOME SORT OF LOFTY FINAL BOSS!! THIS IS WHAT YOU WANTED TO ACCOMPLISH BY FOOLING EVERYONE!? WHAT A LOAD OF BULLSHIT!! ESSENTIALLY, WE'RE IN THIS MESS BECAUSE WE'RE BEING MANIPULATED BY THAT THING, RIGHT!? THEN DESTROYING IT WILL SOLVE EVERYTHING, WON'T IT!? I WILL DO IT MYSELF!! I'LL WRECK UP THIS WHOLE FUCKED UP DEVELOPMENT!! I'M GOING TO DESTROY IT ALL!!! AND I'M GOING TO SAVE THE WORLD!!!!
Yandere: A rare male example: Riku, concerning Amane. A classmate who spoke bad of her ended up in hospital after Riku had a Heroic BSOD.
